Assembled bone implants

ABSTRACT

This invention provides a method for manufacture of autograft, allograft and xenograft implants which comprises assembling such implants from smaller pieces of graft materials to form a larger graft implant product.

FIG. 1 shows an exploded, perspective view of a first embodiment of the assembled bone implant showing our design. The design comprises first and second cylindrical ends. Between the first and second cylindrical ends are first and second cylindrical pins attaching the first and second cylindrical ends.

FIG. 2 shows a perspective view of the embodiment shown in FIG. 1 as assembled.

FIG. 3 shows an exploded, perspective view of a second embodiment of assembled bone implant showing our design. The design comprises first and second cylindrical ends and a center cylindrical segment which are attached together by cylindrical pins to form an assembled dowel shaped bone implant. The center cylindrical segment is made of cancellous bone, and the cylindrical ends are made of cortical bone, or vice versa.

FIG. 4 shows a perspective view of the embodiment shown in FIG. 3 as assembled.

FIG. 5 shows an end plan view of the embodiment shown in FIG. 4. Section lines A—A and B—B are not claimed as part of the subject design.

FIG. 6 shows a cross-sectional view of the embodiment shown in FIG. 4 along section line A—A as shown in FIG. 5; and,

FIG. 7 shows a cross-sectional view of the embodiment shown in FIG. 4 along section line B—B as shown in FIG. 5. 

The ornamental design for an assembled bone implant, substantially as shown and dsecribed.
